New research into the dynamics and structure of high-temperature liquid uranium trichloride (UCl₃) salt—a potential fuel for molten salt reactors—has been published in the Journal of the American Chemical Society. A recent news release from Oak Ridge National Laboratory describes how researchers from ORNL, Argonne National Laboratory, and the University of South Carolina used ORNL’s Spallation Neutron Source (SNS) to document the unique chemistry of liquid UCl₃ “for the first time.”

Start talking about dust in a vacuum, and some people will think of household chores. But dust has featured in recent nuclear science and engineering headlines in curious ways: ITER is deploying oversized dust covers inspired by space satellites in the south of France, while at Yale University, researchers have watched every move of a dust-sized particle levitating in a laser beam for telltale twitches that indicate radioactive decay.

The U.S. Nuclear Regulatory Commission began a special inspection last week at South Texas Project nuclear power plant into two incidents at the site, which led to separate, unplanned shutdowns of both Units 1 and 2.

• On May 12, a transformer that supplies off-site power to the station shut down unexpectedly and took Unit 2 off line.
• On July 24, a fire in an electrical switchyard at the site caused an unplanned shutdown of Unit 1.

The American Nuclear Society recently selected two of its members to serve as the 2025 Glenn T. Seaborg Congressional Science and Engineering Fellows. The 2025 Congressional Fellows, Jacob Christensen and Mike Woosley, will help the Society fulfill its strategic goal of enhancing nuclear policy by working in the halls of Congress, either in a congressional member’s personal office or with a committee, when their fellowship term begins in January.

A new article in the Wall Street Journal focuses on the problematic confluence of three developments: a declining number of young people pursuing nuclear engineering, an aging nuclear workforce with many workers on the verge of retirement, and a growing demand for nuclear energy. Reporter Yusuf Khan, who specializes in sustainability-related issues, examines the nuclear industry’s “image problem” and also the roles of climate change concerns, advanced nuclear technologies, artificial intelligence, and workforce diversification in bringing hope for a reinvigorated industry.

The recent decision by the U.S. Supreme Court to overturn the Chevron doctrine marks a significant shift in the landscape of federal decision-making. For more than 40 years, this doctrine has provided a framework wherein courts deferred to federal agencies’ interpretations of ambiguous laws in recognition of the specialized expertise these agencies bring to policy and regulatory development.

The Volunteer State’s governor and representatives have made clear their intention to position Tennessee at the forefront of a nuclear energy growth surge over the next several years. They’re making the financial investment to back up this commitment, pledging $50 million to recruit the innovative and invest in the existing nuclear companies in the state.

In an interview with advocacy group Nuclear Matters, Gov. Bill Lee expressed his excitement and optimism for Tennessee’s nuclear future.

“Tennessee is one of the fastest growing states in the country,” he said. “Because of that, we have people and companies moving here and we need to have a dependable, reliable energy source.”

The U.S. Senate’s Environment and Public Works Committee spent more than an hour questioning Matthew Marzano on Wednesday as part of his nomination process to become a commissioner of the U.S. Nuclear Regulatory Commission.

The Department of Energy’s Office of Nuclear Energy has released a new report estimating that there may be the potential to install 60 GWe–95 GWe of new capacity at currently operating and recently retired nuclear power plants in the United States. The report also evaluated the potential of building new nuclear plants near current and retired coal power plants. The report, titled Evaluation of Nuclear Power Plant and Coal Power Plant Sites for New Nuclear Capacity, was prepared as part of DOE-NE’s Systems Analysis and Integration (SA&I) campaign.

Idaho National Laboratory has completed substantial construction of the first new hot cell facility at the lab site in 49 years—a Sample Preparation Laboratory (SPL) that will accelerate research, development, and qualification of structural nuclear materials for both existing and new nuclear reactors. In an announcement last week of the milestone and the ribbon-cutting ceremony held to mark it, INL said the SPL is expected to be fully operational in 2025.

When a SpaceX rocket lifted off from Kennedy Space Center on September 10 (see video here), sending a crewed commercial mission into low Earth orbit, an experiment designed by Pacific Northwest National Laboratory was onboard. Several high-purity metal samples will orbit Earth and absorb cosmic radiation for five days—including that from the Van Allen radiation belt—to help the lab answer questions about the radiation environment for manned space missions, according to a news release from PNNL.

The American Nuclear Society was formed in 1954 in the wake of President Eisenhower’s seminal Atoms for Peace speech. Around the same time that Congress was debating the Atomic Energy Act and John Landis was helping establish ANS, the National Security Council began deliberating about adding a nuclear-­powered merchant ship to the nascent Atoms for Peace program. We like to imagine that the idea germinated after Mamie Eisenhower christened the U.S.S. Nautilus, but the truth seems much drier. Regardless, Ike championed the project and announced it to a surprised crowd in an April 1955 speech in New York City at the Waldorf Astoria Hotel. Landis would become the principal architect of the ship’s nuclear power plant. Although Savannah’s reactor now rests in the low-level radwaste repository in Clive, Utah, the ship’s prospects are as bright as the future of ANS itself.

EnergySolutions announced that it has launched Management Consultants International (MCI) to provide specialized consulting services for the nuclear, energy, chemical, oil, gas, technology, and manufacturing sectors. Operating separately from EnergySolutions, MCI will provide expertise to clients addressing multiplex issues before federal, state, and international agencies.

Nuclear industry veteran Pierre Oneid has been appointed president of MCI. He will also continue in his current role as executive vice president supporting EnergySolutions’ growth efforts. Formerly senior vice president and chief nuclear officer for Holtec International, Oneid joined EnergySolutions in May of this year.

According to the Department of Energy’s Office of Environmental Management, two contractors at its Hanford Site in Washington state have finished a first-time relay of test glass as the site prepares to vitrify—or immobilize in glass—millions of gallons of radioactive and chemical waste from its large underground tanks.

The American Nuclear Society recently issued an open letter in support of a science-based approach to the regulation of high-assay low-enriched uranium (HALEU) fuels for commercial nuclear energy, voicing member concerns about hyperbole in a recent article published in Science, which advocated for restrictions on the use of HALEU despite decades of effective safeguards and security. This is not the first time ANS has stepped in to present the measured opinion of its membership on the value and appropriate regulation of HALEU.

The American Nuclear Society and the Nuclear Energy Institute have announced a new partnership regarding two of their flagship industry conferences.

ANS’s annual Utility Working Conference and Vendor Technology Expo and NEI’s Nuclear Energy Assembly will merge during the week of September 8, 2025, in Atlanta, Ga. The news was shared during the kickoff of the 2024 NEA meeting, happening this week in Philadelphia, Pa.

The International Atomic Energy Agency has found that Japan’s planned approach for recycling and disposing of soil and radioactive waste from decontamination activities after the 2011 Fukushima Daiichi nuclear accident is consistent with the agency’s safety standards.

Current and future decarbonization goals necessitate robust and reliable energy generation solutions with high capacity factors to serve as baseload sources of clean energy. Next-generation advanced reactor and small modular reactor designs have driven new technology, training regimes, and new reactor design and implementation of solutions associated with new design concepts and scale.

Research and teaching institutions like Washington State University are responding to help meet the needs of future nuclear research and development and fill in workforce gaps by preparing the next generation of workers in nuclear science and engineering. Domestic university research reactors provide an unparalleled teaching and training tool and are an R&D force multiplier for enhanced nuclear skillset development and training. Investing in research reactors and the important mission they serve benefits nuclear research both domestically and globally. Research reactors offer low-cost, safe, real-world job training and provide the experimentation platforms necessary to advance and meet demands of ongoing and future work in the nuclear sector that transcends traditional nuclear R&D.

Ian Wall early in his career . . .

I graduated with a degree in mechanical engineering from Imperial College, London, in 1958. Nuclear power was viewed favorably at the time, so I took a 1-year course on the subject. I was then offered fellowships at Cambridge University and the Massachusetts Institute of Technology and thought the latter would be more interesting, so I moved to Cambridge, Mass., to study nuclear engineering. After completing my doctorate in 1964, I joined the American Nuclear Society and took a job with General Electric, then in San Jose, Calif.

In 1967, GE assigned me to explore the use of probability in reactor safety. At that time, the prevailing opinion was that the probability of a severe accident was infinitesimally small and the consequences would be catastrophic.

Westinghouse Electric Company announced today that it has signed a teaming agreement with Hyundai Engineering & Construction Company to pursue opportunities in Sweden and Finland for nuclear power plants based on Westinghouse’s AP1000 reactor technology.
